SPECIFICATION forming part of Letters Patent No. 418,553, dated December31, 1889.

' Application filed May 25, 1889. Serial No. 312,112. (No model.)

To all whom t may concern:

Be it knownjthat I, CHARLES C. CHAMBER- LAIN, a citizen oftheUnitedStates, residing at Muskegon, in the county of Muskegon and Stateof Michigan, haveinvented; certain new and useful Improvements inCuspidors; and I do. declare the following'y to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertain's to make and use the same, referencebeing had to theaccompanying drawthereon, which form a part of thisspecification.

The invention relates to improvements in cuspidors, the object being toproduce an article of the kind of paper or other suitable materialrendered by any suitable means water-proof, and also preferablypartially 'fire-proof, so that it will not easily burn and which can' beflattened or knocked down for the purpose of rendering it less bulky andoccupying less space during transportation; and it consists in thepoints of construction hereinafter described, illustrated in theaccompanying drawings,`and pointed out in the y claimhereto appended.

. Referring to the drawings by letter, A, Fig.

l, designates the circular blank of which the cuspidor is made' andwhich consists, preferably, of suitably thick paper rendered waterproofand, preferably, partiallyre-proof by any proper means, so4 that it`Will not burn readily unless thrown into a stove orfurnace. The saidblank `has extending inward from it-sedge to the circular innerpartition a, in-

` tended to form the base of the cuspidor, the

score-marks a d2, each score a forming an elongated V-shaped spaceorffigure a3 with the adjoining score a2, the vertex of which space isinward. The said spaces a3 are not radial to the blank, but all inclinedat equal angles and in the same direction tothe radiiv thatwouldotherwise bisect them, the scores a2 inclining sufficiently morethan the scores. ct to make the spaces a3 V-shaped in the proper degreeto permit said spaces a3 to be turned over on the intervening spaces 0,4of the blank and form plaits therewith when the blank is operated uponby a suitable forming-machine.

The described construction is plainly and fully shown in Fig. l of thedrawings.

Therblank when knocked into shape by a machine forming no part of thisinvention,

but which is subject-matter for an application of even date of filingherewith, appears as shownA in the side view, Fig. 3, in which thecnspidor tapers inward from the base a, as at B, to a circular neck b,and thence flares or inclines upward and outward, as at Z9', the part Bforming a conical frustum below the neck b and the part bf forming areversed conical yfrustum above said neck. In Fig. 3 the plaits areshown completed, the V-shaped spaces A3 being folded down on theintervening spaces a4. tant and, on account of the described inclinationof the V-shaped spaces, incline upward from base to top ofthe cuspidorat equal angles, so that by twisting the top of the latter on the basethereof the inclination of the plaits can be largely increased and thecuspidor' flatten ed or knocked down, thereby decreased in bulk for thepurpose of transportation,the paper having suflicient elasticity toassume its normal and proper shape when unpacked. The plaits may, whenformed, have their sides or leaves held together by any proper means;but it is preferable to hold i The said plaits areequidisf' bind on eachother, besides binding in the Y IOO last about two days, when they mayWithout cleaning be burned in a stove or furnace or otherwise destroyed.

The invention is simple and effective and 5 fully answers the purposefor which it was designed.

Having described my invention, l claim- The circular cuspidor-blank A,having the circular interior base portion a, and the in- Io clinedequidistant V-shaped spaces a3, ex-

tending from the circumference to said base portion and composed of theadjacent inclined scores a a2, substantially as specified.

In testimony whereof I affix my signature in presence of two Witnesses.

CHARLES C. CHAMBERLAIN.
